In my experience I have found and figured out that the plastic is too soft to be able to effectively smooth out the scratches and remove them. The best thing to disguise them that I have found is Pledge furniture polish. I have tried everything imaginable and that is my suggestion. I also have come to realize that the only way to keep scratches off of them is to not ride them. lol
I have found a product called plastic gloss made by nova industries. You spray it on and leave it. It make you plastic look brand new. The scratches are still there but not visable and it shines like brand new. Also it forms a barrier so that the next time you clean your bike the mud and dirt just falls off. Highly recomend it. It's made up here in Canada so you know it's good.
